Well folks, after 4000km, my Skyteam decided to give me his first grin. The two bolts that hold the stator coils assembly got loose and the coils started rubbing against the flywheel:





I neglected the rattling from the left side of the engine and today it stopped...

I think it's a "standard" OHC Honda clone engine (has 166FMM code on it):



Any suggestions where I can get new assembly from, as I can't find anything suitable in ebay (or google in general)?
